This visualization presents a family tree as a horizontal dendrogram, with nodes connected by orange links and labeled with names from a JSON dataset. Node color encodes different branches of the lineage, while font size decreases with each generation to show depth. The example uses D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` components to compute the layout, with SVG rendering and zoom functionality enabled via D3’s `zoom` and `event` APIs. The visualization is built within a React framework, and text elements are styled with a Playfair Display font.
